Dear candidate, you should check the eligibility criteria of that particular post-graduation course. Example: The entrance exam of MBA is CAT which requires graduation in any course. However, M.Tech, MSc, MA are some courses that need graduation in a particular domain. Some PG courses related to fashion designing you can pursue are:

• M.Des (Master of Designing)
• MFA-Fashion Design (Master of Fine Arts)
• MA-Fashion Design (Master of Arts)

Do check eligibility criteria of the post-graduation course you want to pursue.

Hope, it helps!
